Front Cover: In article 2400178, Alexandra Pulyalina and and co-workers report on the development of polymer membranes based on new copolyamide and its complex with copper(II), providing selective transport of methanol in separation of organic media. Preferential mass transfer of methanol occurs due to the creation of specific channels by forming multi-hydrogen bonds between methanol and macromolecules. Based on detailed studies of the structure and physicochemical properties, it was shown that the developed membrane materials are suitable for practical use.
